SHIP-PROTECTOR.

Specification of Letters Patent.

Application filed August 5, 1918. Serial No. 248,443.

To all whom it may concern:

Be it known that I, FRANK HANsEN, a citizen of the United States, residing at Breslau, in the county of Pierce and State of Nebraska, have invented new and useful Improvements in Ship-Protectors, of which the following is a specification.

This invention relates to a means for temporarily stopping holes in marine vessels, as when the same has been struck by a torpedo, to prevent the inrush of water and permit of the ships carpenter repairing the vessel so that the same will be prevented from sinking.

I accomplish the foregoing objects and others which will appear as the nature of the invention is better understood, by a construction, combination and operative arrangement of parts, a simple and satisfactory exemplification of which being illustrated by the drawings.

The nature of the invention is such that the same is necessarily susceptible to various modifications, all of which, however, fall within the scope of what is claimed.

In the drawings:

Figure 1 is a side elevation of a marine vessel equipped with the improvement, the valve or patch plate being in its normal inoperative position;

Fig. 2 is a similar view but showing the valve or patch plate in its operative position a Fig. 3 is a sectional view approximately on the line 33 of Fig. 1';

Fig. 4 is a similar view approximately on the line 44 of Fig. 2;

Fig. 5 is a perspective view of the carriage; and

Fig. 6 is a similar View of the valve or patch plate.

In the drawings the numeral 1 designates any ordinary construction of marine vessels, such as a warship, convoy, merchantman, or the like. Upon the sides of the vessel 1 there is secured a substantially L-shaped track 2, the outer vertical member of the said track having its inner edge inturned providing a flange 3. On this track travels a carriage 4. Before proceeding with the description of the carriage it should be stated that any desired number of such carriages may be employed, and also that the track extends entirely around the vessel. The carriage, in the showing of the drawings is in the nature of a substantially rectangular frame suitably braced to render the same strong and effective for the purpose intended, but not sufficiently heavy as to interfere with the proper balancing of the ship or the free movement of the carriage from the track. The carriage 4, at its upper and lower edges is formed with inturned arms 5 and 6 respectively, the arms 5 being arranged above the track 2 and the arms 6 be ing arranged below the said track. These arms each carry anti-frictional rollers 7 and 8 respectively, which contact with the sides of the vessel. The frame, comprising the carriage 4 is provided with a central arm 9 of a less length than the arms 5 and 6, and this arm has its inner end provided with a dependin portion 10. The portion 10 has:

journale thereon transversely arranged rollers 11 and 12 respectively, the rollers 11 engaging with the horizontal portion 13 of the track 2, the rollers 12 contacting with the vertical straight portion 2 of the track directly below the inturned flange 3 thereof. The carriage has secured thereto,*upon its opposite ends guide ropes 14 which are arranged on the deck of the vessel and which provide means whereby the said carr age may be moved longitudinally in either d1rection of the vessel and held in proper position on the vessel.

On the carriage12, below the arms 6 is arranged a shaft 15 which has journaled thereon eyes 16 formed on the corners of a flat plate 17 This plate may have its inner edges formed With flanges 18 and may be centrally ribbed or braced as at 19. On the flange 18 are secured compressible and if desirable adhesive strips 20. The inner-face of the plate 17 is, it will be noted, of a hollow formation, the strips 20 entirely surrounding the plate, and the plate 19 prov ides a valve or patch plate and is normally held in its upper vertical position by being swung against the carriage 4. To accomplish this the inner face of the plate has swiveled thereon a pulley 21, and the outer face of the carriage 4 is likewise provided with a pulley 22. Trained around these pulleys is a cable or rope 23 that has its free end secured on the deck of the vessel as at 24. By reference to the drawings it will be noted that the portions of the valve or patch plate provided with the eyes 16 are arranged at an angle with respect to the plate proper, as indicated by the numerals 25, and inaddition to this the pulleys 21 and 22 serve to Patented Feb. 11, 1919.

retain the plate 17 a slight distance outward of the carriage at. The plate is suflieiently weighted so that the same will automatically swing in a downward direction when the cable 24: is released, and the curved portions 25 permit of the strips 20 contacting with the sides of the vessel.

The carriage is normally so arranged and the valve is of such size that the same will cover the vulnerable part of the vessel when brought directly thereover, but if desired the hinge connection between the plate 17 and the carriage may be adjusted. Should a torpedo strike the vessel or the vessel contact with an obstacle so as to stave in the side thereof, the carriage is moved to bring the same directly over the hole or opening thus made. The holdino' cable for the valve or patch plate 17 is reIeased. The weight of the plate, as previously stated, will cause the same to drop in the water. The inflow of water rushing into the hold contacting with the outer fiat face of the plate will force the same tightly against the side of the vessel,- over the hole, thus at least temporarily closing the hole and permittingthe actuation of the pumps to remove the water from the interior of the vessel and permit of the carpenter temporarily closing the hole so that the vessel will be prevented from sinking and may, under its own power proceed on its voyage.

Having thus described the invention, what is claimed as new, is 2-- 1. In a device for the purpose set forth, a vessel, a track thereon, a carriage slidable on said track, and a hinged patch plate on said carriage.

2. In a device for the purpose set forth, a vessel, a track surrounding and secured thereto, a carriage slidable on said track, anti-frictional elements between the carriage and the track and between the carriage and the Vessel, a patch plate having an offset end pivoted to said carriage, and means for re taining said plate against said carriage.

3. In a device for the purpose set forth, a vessel, an L-shaped track secured to the sides thereof above the water line, a carriage having anti-frictional members engaging the said L- shaped track and having antifrictional elements engaging with the sides of the vessel, a patch plate having, offset portions hingedly. secured to the carriage, said plate having one of its faces flanged and the said flanges provided with a strip of compressible adhesive material, means for sliding the carriage longitudinally of the ves sel, and means for normally sustaining the plate against the carriage. I V

' 4. In a device for the purpose set forth, a vessel, an angle track on the side of said vessel having its upper edge provided with an inturned flange, a carriage slidableon the side of the vessel and on said track, comprising a rectangular member having, upper and lower arms disposed above and below the track, anti-frictional elements on said arms contacting. with the sides of the vessel, said; carriage; having a horizontal providedwith a downturned end, angularly disposed anti-frictional rollers on said end engaging with the track and below the flange thereof respectively, a plate having angular sides hingedly connected to the lower portion of the carriage, said plate having one of its faces flanged, ribs between the flanges, a strip of compressible and adhesive material on the flanges, means for normally sustaining said plate against the carriage, and means for moving the carriagelongitudinally of the track. r V r In testimony whereof I affixmy signature.
